'lhese metal segments 4o are held in pluee by bolts lt. bieb pass through depressed holes in the metal segmente, and loan through the wood eoustituting part of the. detleetor, and through the lllt Supporting tiltl it 'ltit'lt lllt u'mul is' se cured. These bolts may have their nuts either at one side or the otberof the detleetor, but l prefer to have them on the upper aitle,tind it is desirable to have both the nuts-'f' and headsmumterstmk below their respeetive lurfaceaof the delleetor. as shoun. so as not t0 forman obstruetion in seenring elose operating punitions between these sttrfnees and Y other parts.

Around on the internal, .bore of the deileetor, in position approximately one-third of the distanee upward frotn tbe lower side of the delleetor, l provide an annular grooveshaped trough or ehannel W, of wood, as`

shown in Figs. and 4, with eross partitions au X at quite elose intervals, and in the bottom of this trough.,extending radiall through the delleeto to itsotttside snrl'a'ee. l provide a circumferential row of |arforntions Y Fig. 4--for the passage of \\'nter from sid u trough to appropriate portions of the sepaA 'l`lte detleetor-'is rotated differentially to tbe treatment vessel an'd se mrating sarlat-e, as uell as to the feed or feed distrihntin' deviee or means aml distributing ebannes or means, the revolving trough, and some other parts, whit-b are hereinafter more fully deserilzed. through the use of a rope belt that ma)I he supplied and operated around the sbeave l.. 'lhe delleetor in its differential rot-ation .serves to assist in the even distribution of material over the separating surfaee, and also, beeause of its diferential rotation to the separating surfaee and to the material beingde|msited on sueh surface. frietionally generates and transmits through the iinstrumentality of the body of unter in the separating ehaunel au aqueous seom'ing foree to assist in separation of said material, as \vell asin the removal of its various protlttets.

'l`lie tttlies'sucres-tively inerease suilieiently in diameter from the sleeve outward to leave t-that the top side of one disk serves as the a suitable annular feed passieve hetwccn..

'l have 'ini-A tnlh of them, which passage tialed 4.

arc threaded at their lower ends, and cael' enters into and engages with the screw threads in the central bore of a correspon-.ding disk--tha sleeve engaging the lower disk. The 'several disks are imlicated numeral o, and are assembled one above the other in close contact, as shown, and at right angles with the tubes: 'lhey extend ont. dialuctrically a considerable distance, and all, except the bottom one, are provided with ribs (Lou their lower sides, asillustrtttcd.

The ribs of each disk at their inner cods are preferably spaced at substantially equal distances apart throughout the circumference of the central bore of their disk, and extend therefrom in dctlectcd radial courses at. suhstantially right, angles to the axis.--as also especially shown in detail in Figs. l2, i3, I4 and 17--preferably to the outer dtnneter of said disk, terminating in two preferably diametricallyopposite groups, each group embracing a desired portion or zone of the circumference of the disk.

Between the ribs are located channels. 7, for the llow of water and material, so that the channels for cach disk radiate from thc inner circumference of its central bore, which is substantiallv the outer circumference of the bottom ofthe respective feed receiving passages, and terminate preferably in the two diamctritally opposite groups at the outside portion of the d|sk.each group cmhracing a multiplicity of channels covering preferably, about one-sixth of the total circumference of the d isk or tield of rotation of the feed device, and servingl as means for rceeiving clean water. or material for se aration commingled with water. that is fet into thc separate feed mssagcs -l, and delivering it with practica ly uniform distribution throughout the particular segmental zones embraced by the channels from the respective feed passages. These groups of terminals of said channels substantially determine the location and extent of the several zones of dill'erent und of like action in the separator, because said groups of channels feed or distribute the appropriate elements in or for said zones, thereby initially establishin these ditl'erent zones within predeterxnine ditl'erent circumferentiallv travelahle segmental portions ot' the ticld ol' rotation of the treatment vessel, embracing corresponding, and therefore |n'cdelcrmimd circumferentially travclablc segmental parts or areas on the separating surface. As shown, these ribs and channels are located on the under side of the disks, and I have placed 'one disk above the other in contact, as above stated,' and have secured theta together so by thc Ime of the feed passages 4. Ihe sleeve /i and each of the short tubes l bottom ol the channels directly above it, and also as the bottom of the corrcs|mndin To assist in hohlz ing the short tuhcs and the central sleeve strongly together and rclativelv in p ace, have provided several stud bolts S--shown most clearly in Figs. 2, ti. 7 and et threaded through the walls of the several tubes, transversely to said walls. and have extended them to. and eagagedthem with the central sleeve.

ln assembling the disks l have done so with reference to the wroups of outer terminals of their feed c nanucls as shown especially in Fig. ti, so that the several se",- mcnlal groups or zones of channels will etillectively form a continuons zone or field of thcsc channels throughout the circumference of the collective disks, into their respective feed passages 4, for ditl'erent purposes in the separator, will be delivered out within their zonescorresponding segmental or part-s of the liehl of rotation of the feed device at the circumference of the. collective dislcs, and from there. by additional agencies hereinafterdescribed, will he carried out through the several corresponding segmental zones within the liehl of rotation of the treatment vessel to and deposited on the corresponding segmental areas of the scparatin f surface included within said zone, whic i zones are. embraced between substantiallyradial lilies transversely to the axis from their respective segmental feed zones at the. circumference of the feed disks. It therefore follows that during operation, the volume or quantity of tlow into any of the said feed passages, nud consequent deliver)l on thc respective parts or areas of the. separating surface within the several segmental zoncs nml the llow through the corres )onding parts of the separating channel whille the separator is at aconstant speed of rotation,.may be varied Y and regulated irrespective of the llow within other Vannes, there being facility tln'otwh secondarv discharge holes hereinafter t eseribed, for increasing the discharge ca aeity from desired segmental portions o said channel while said portions arewithin zones of action requiring such increased ilow.

l have. placed Figs. l2, I3 and i4 on their sheet of the. drawings in relative circumferential positions, each illustrating the feed channels of a separate disk, so that collect- ,ivcly they embrace the entire circumferlcntml held of action wtthm the sentrator,

and if the several disks were assent ed one on top of the other (as shown in Fig. ti) in the relative circumfercntial positions illustrated, the terminals of their channels would collectively embrace the entire circumference of thel assembled disks and that of their entire field of rotation.

After the mi illings have been removed within the middlinge removing zones, and discharged, aa haa been hereinabove ex plainod, there will unl-Irv remain concentrates on the ee aratin au ace aait progressively entergea oriva from these zones into the adjacent concentrates-rettioving zones.' where they are subjected to a siillieiently strong Bow of water to wash and remove them from the separating surface and carry them to discharge into their appropriate circumferential portion of tbe revolving trough, from whence they will be thrown through tho appropriate nipples in said trough into their compartments in the fixed lnunder, and tlowed from there separately with their water for dia ition to any desired place.

Aa t e veeael carrying tbo se uniting eiirface and the retaining plate i, with the valve roda and their iulrrumed lovers, rotatea ditlerentially with relation to the revolving trough, and aa the apokea of said trough ca the aboea 40 --wbirli bitter are loeated wit in the scope of the segmental middhnga and concentrates-removing zones in o ration, it follows that the valve roda as t iey enter tlieee zones are drawn inward aud the secondary disrharge passages within these zones are o neil, as has been deacri'bed, to enable t ic proper discharge of the greater volume of water required for renewal of these products. After portions of the separating surface have passed through the iieveral aonea, aa explained,the eoneentrateii having been removed-fsurh portions are ready to again progreaaively enter the` Ai'naterial-reeeivinir and separating zones und 'again per! omi their purposes iu'tbe eyele ot' pperation, with the result that separation in its incipient, progressive, und inishing atagea, an the removill und separate discharge of the vanoua produrre, is veonataiitly and uninterruptedly bring areoiuplislicd.
